Group Supplier Rankings

Most of the supplier selection practices involve the participation of multiple DMs and the ultimate decision is based on the aggregation of DMs individual judgments to arrive at a group decision. We have aggregated the preferences of the four DMs using different group decision making techniques discussed in Chapter 6, Section 6.3.9  

The top five suppliers identified by the aforementioned group decision-making methods are presented in Table 7.19. 

It is to be noted that the exact ranking of the suppliers can vary by different methods. However, the objective of Phase 1 is to short-list the promising suppliers. Hence, the list can be expanded when there are conflicts in the rankings.

Supplier 19 came in the first place in both individual and group decision making rankings.
